Hi I cant start a hvm domU with more than 3 nic's configured... why? it is a bug? With previous versions it was possible... here the config - it is an opnsense (openbsd) hvm domU: name = "fenrir.chao5.int" uuid = "7aedcd03-54e8-4055-8d1b-37dd34194859" maxmem = 2048 memory = 2048 loader = '/usr/lib64/xen/boot/hvmloader' type = "hvm" vcpus = 2 rtc_timeoffset = 0 localtime = 1 on_poweroff = "destroy" on_reboot = "restart" on_crash = "restart" vnc = 1 vncunused = 0 vncdisplay = 100 vnclisten = "0.0.0.0" keymap = "de" vif = [ "mac=00:16:3e:05:30:04,bridge=xenbr5,script=vif-bridge,model=e1000", "mac=00:16:3e:04:30:04,bridge=xenbr4,script=vif-bridge,model=e1000", "mac=00:16:3e:15:30:04,bridge=xenbr15,script=vif-bridge,model=e1000", "mac=00:16:3e:14:30:04,bridge=xenbr14,script=vif-bridge,model=e1000" ] parallel = "none" serial = "none" disk = [ "phy:/dev/vg_lamia/lv_fenrir_root,hda,rw", "phy:/dev/vg_lamia/lv_fenrir_swap,hdb,rw" ] pci_power_mgmt=1 xen_platform_pci=1 pci_msitranslate=1 viridian=0 hpet=1 acpi=1 apic=1 pae=1 pvh=1 with 3 nic's it does work... -- ------ Greetz
It seems to be a problem with kernel... I use the kernel-ml there (5.5.6)... with kernel from centos-virt repo (4.9.*) it works without this problem... --- ------ Greetz Am 27.02.2020 07:50, schrieb Christoph:> Hi > > I cant start a hvm domU with more than 3 nic's configured... why? it is > a bug? > With previous versions it was possible... > > here the config - it is an opnsense (openbsd) hvm domU: > > name = "fenrir.chao5.int" > uuid = "7aedcd03-54e8-4055-8d1b-37dd34194859" > maxmem = 2048 > memory = 2048 > loader = '/usr/lib64/xen/boot/hvmloader' > type = "hvm" > vcpus = 2 > rtc_timeoffset = 0 > localtime = 1 > on_poweroff = "destroy" > on_reboot = "restart" > on_crash = "restart" > vnc = 1 > vncunused = 0 > vncdisplay = 100 > vnclisten = "0.0.0.0" > keymap = "de" > vif = [ > "mac=00:16:3e:05:30:04,bridge=xenbr5,script=vif-bridge,model=e1000", > "mac=00:16:3e:04:30:04,bridge=xenbr4,script=vif-bridge,model=e1000", > "mac=00:16:3e:15:30:04,bridge=xenbr15,script=vif-bridge,model=e1000", > "mac=00:16:3e:14:30:04,bridge=xenbr14,script=vif-bridge,model=e1000" ] > parallel = "none" > serial = "none" > disk = [ "phy:/dev/vg_lamia/lv_fenrir_root,hda,rw", > "phy:/dev/vg_lamia/lv_fenrir_swap,hdb,rw" ] > pci_power_mgmt=1 > xen_platform_pci=1 > pci_msitranslate=1 > viridian=0 > hpet=1 > acpi=1 > apic=1 > pae=1 > pvh=1 > > with 3 nic's it does work... > -- > ------ > Greetz > _______________________________________________ > CentOS-virt mailing list > CentOS-virt at centos.org > https://lists.centos.org/mailman/listinfo/centos-virt

If you can't find any evidence the bug has been reported or fixed already, I would encourage you to do so on the xen-devel mailing list since Linux 4.9 won't be supported forever. But in addition to the example configuration file, you may need to provide details about exactly what happens with 4 NICs to get a useful response. The output from running the xl create command, the kernel log, or the xen-hotplug log would likely contain more information. --Sarah
